Pseudo-spherical normal Darboux images of curves on a timelike surface in three dimensional Lorentz–Minkowski space
(ElsevierAmsterdam, 2015-11)
In this paper we introduce the notion of pseudo-spherical normal Darboux images of curves on a timelike surface in three dimensional Lorentz–Minkowski space. We investigate the singularities and geometric properties of ...
Comment on "The surface potential of a spherical colloid particle: Functional theoretical approach"
(Academic Press Inc Elsevier Science, 2006-12)
In a work published in this journal by Z.W. Wang, G.Z. Li, D.R. Guan, X.Z. Yi, and A.J. Lou [J. Colloid Interface Sci. 246 (2002) 302], an iterative method for the determination of the potential around a colloidal particle ...
Surface temperature distribution on a spherical ice particle growing by accretion in wet growth regime
(John Wiley & Sons Ltd, 2019-10)
Experimental evidence has demonstrated that temperature on the surface of an ice particle growing by accretion is not uniform. This non-uniformity is relevant because the ice particle surface temperature is an important ...

Phase Field Modeling of Dendritic Growth on Spherical Surfaces
(Frontiers Media, 2020-06-03)
The spontaneous formation of a crystal phase is one of the most common and beautiful pattern formation mechanisms in nature. Different instabilities in the crystal interface may lead to the growth of ramified structures, ...
O funcionamento do GPS e a matemática do ensino médio
(Universidade Federal de São CarlosUFSCarPrograma de Mestrado Profissional em Matemática em Rede Nacional - PROFMATCâmpus São Carlos, 2015-08-21)
The main objective of this work is to make students understand the mathematical foundations for the operation of Global Positioning System (GPS). The research was done in a school in the state of São Paulo with students ...
Preparation and characterization of spherical silica-porphyrin catalysts obtained by the sol-gel methodology
(Elsevier B.V., 2006-03-01)
This work describes the synthesis of a first-generation iron porphyrin catalyst entrapped in a silica matrix by the sol-gel route, leading to spherical particles. The catalyst was synthesized by the method of Stober, through ...
